Title: Improvements in iron recovery
IPC: C22B1/16
Filed: 1953-05-11
Abstract: A process for reducing iron oxide ores comprises mixing iron oxide ore, scrap iron, fluxing material, and solid carbonaceous material, heating the mixture to the sintering temperature to effect (1) reduction to metal of at least a part of the ore, (2) chemical combination of part of the unreduced oxide, fluxing material, and gangue, and (3) the production of a granular free flowing product, placing the granular product on the surface of a molten slag bath, maintaining the slag at a temperature high enough to provide all the heat required to reduce the ore, and then separating the molten metal from the slag.  The granular product may be fed on to the molten slag bath in an electric furnace, the electrodes of which heat the slag by arc-resistance heating, and which are maintained between 1/2 inch above and 2 inch below the surface of the slag.  The sintering may be performed in a rotary kiln and the granular product fed to the electric furnace without loss of heat.  The amount of carbonaceous material may be that required to reduce the ore and produce a molten metal containing not more than 2 per cent carbon.  All the carbonaceous material may be added with the sinter or part with the sinter and part directly to the electric furnace.  The slag used may contain 0,7-1,5 molecules lime to 1 molecule silica.

Abstract: 786,293. Etching. BIRMETALS, Ltd. May 7, 1956 [May 6, 1955], No. 13143/55. Class 100(2) A traversing gear assembly in an etching machine comprises means for oscillating about its own axis a carrier for a plate such as a metal printing plate, to be etched, means for moving the axis in a prescribed path, and means for progressing by a pre-determined amount the position on the path at which reversal of the oscillating motion occurs. An electric motor 12, Fig. 1, drives through an overload clutch 18, 17 a hollow shaft 14 to which is fixed an arm 19, which is thereby rotatable about a main axis 28, and which carries a spindle 21, Figs. 1 and 2, to which is secured a plate carrier 22, the spindle 21 having a pinion 23 fixed thereto. The spindle 21 extends through an opening in a baffle 37 which is rotatable about the axis 28 as the spindle 21 is moved in a circular path by the arm 19, so that the carrier 22 projects into an etching bath wherein etching liquid is splashed by paddles rotating on horizontal axes or sprayed against the plate. A gear quadrant 24 engages the pinion 23 and is pivoted on a crank pin 27 eccentric to the axis 28 and fixed to a sun gear 30 mounted on a spindle 32 freely rotatable on the shaft 14. A link 25 is pivoted to the spindle 21 and to the gear centre 26 of the quadrant 24. A planetary gear cluster 35 comprises two pinions is rotatably mounted on the arm 19 .and engages the sun gear 30 and a fixed sun gear 34, the gears 30, 34 being of different sizes and having sixtynine and seventy-one teeth respectively, so as slowly to rotate the gear 30, whereby the position on the circular orbit of the spindle 21 at which the oscillation of the spindle is reversed is progressed along the orbit. Taking the radius of the arm 19 from the axis 28 to the spindle 21 as unity, the length of the link 25 from the spindle 21 to the gear centre 26, the distance between the gear centre and the pin 27, and the distance between the pin 27 and the axis 28 are respectively 1, 0.3 and 0.14. To avoid backlash, each of the turning pairs and geared pairs have an element (bearing or pinion) of a superpolyamide synthetic resin such as nylon, which can be operated without working clearances. In another form, Fig. 9, the quadrant and link are replaced by a rack 46 pivoted to the pin 27, engaging the pinion 23, and guided in a guide 47. In another form, Fig. 10, a rod 48 connects the pin 27 to a quadrant 49 pivoted at its gear centre to the arm 19. The gear assembly may be mounted for translational movement bodily at right-angles to the paddle axis.

Title: Improvements in automatic control systems for aircraft
IPC: G05D1/06
Filed: 1956-04-30
Abstract: 825,131. Automatic steering control systems. BENDIX AVIATION CORPORATION. April 30, 1956 [May 13, 1955], No. 13233/56. Class 38 (4). In an aircraft automatic pilot a first electric signal dependent on aircraft displacement from a reference position is applied to an electromechanical device which produces a second signal proportional to the first signal for longterm variations of the first signal but produces no appreciable signal for short-term variations, the two signals assisting each other to restore the aircraft to its reference position. As shown, deviations in the pitch attitude of an aircraft from a value determined by the setting of a manual knob 46, are detected by a gyroscope 10, signals from the inductive pick-off 13 of which are applied through an amplifier 16 to operate a servomotor 18 correcting pitch by adjusting elevators 20. Position and rate follow-up signals are fed back to the input of amplifier 16 from an inductive device 23 and an A.C. generator 25 operated by servomotor 18. To maintain constant altitude a switch 27 is closed to energize an electromagnetic clutch 30 coupling an inductive pick-off 33 to an aneroid bellows so that deviations from the altitude obtaining when switch 27 is closed are automatically corrected by signals from pick-off 33 applied to the input of amplifier 16. Signals from pick-off 33 are also applied through an amplifier 37 to operate a motor 38 which, by virtue of rate feedback from a generator 45, runs at a speed dependent on altitude error. A pick-off 41 adjusted by motor 38 thus applies to the input of amplifier 16 a signal dependent on the integral of altitude error. When knob 46 is moved from a central position to change pitch by adjusting an inductive device 47 to apply a further signal to the input of amplifier 16, a switch 27c is opened to de-energize clutches 30 and remove the altitude and integral of altitude control signals. The resultant control signal is also applied through an amplifier 50 to operate a servomotor 51 which by virtue of positional feedback from an inductive device 53 introduces a further signal dependent on pitch error into the input of amplifier 52. Large rate feedback from a generator 16, however, delays the build-up of this further signal so that it is only effective to combat slowpitch oscillations corresponding to " porpoising " of the aircraft. Specification 662,853 is referred to.
